ille same is true ol the pipes M and valves i/1. '.lhe loiv of the liquor having been rer versed through the several elfeets, the valves i in the passages B to B" are reversed also, and Steam 'is chainhcr S or elleet A by steam-valve EQ i where it condensed, and the Water of condensation escapes by the steam-trap as before.

vapors generated in the evaporatingainher of this elleet pass through passage into the steam-chamber ot' effect A2 and are lensed. 'lhe vapors the evaporatingeinher o? effect if pass by passage B' into c steam-chamber of eli'ect A and are coni "lie vapors trom this effect pass by .nto the steam-chamber oteli'eet A oratinyschaniher of effect A are condensed by condenser F'.

As shown, they are automatic,

and connected oy hars D, so as to normally rios: the i'alvcs (l and C2 and open valve C' in the pass E, B2, and B. respectively, or versa. ln the other passages, B5, and a similar arrangement of valves is enipmyed. The etectof this is that the pressure the steam or vapor operates thevilves au- "lhiis il' the steam is supplied at E the in ipors from eli'ect A force open valve C, close valve i". and open valve C2, and at the same time ihe valves in passages B and B3 are rinsed and in passage B4 the valve is open. i' lhe system is rcversed,the pressures of steam and vapors automatically operate the valves in the manner required to secure proper circulation. 'lhe valves and passages are made larger `when thel vapors passing are less dense, su as to secure the greater area to properlyY operate with the lower pressures.

.t'hile l have indicated the valves m m. as hand-valves, it is evident that they may be si mple cheek-valves with the direction ot' opening' arranged to suit the flow of the liquor.

l have shown myir'ivention applied to a type i el multiple elect known to thetiade as the he strani ai l apor chamhers ot' the several vapors (heat) pmnggf dwong@ is in am@ dim-Bw adjacent im J Swim;

In testimony of which invention I hereunto set my hand.
